摘要: In-situ technique is used to generate cadmium sulfide nanoparticles in PVA matrix. The as-prepared films are characterized by X-ray diffraction, transmission electron microscopy, ultraviolet–visible absorption, Fourier transform infrared spectroscopy and photoluminescence measurements. Temperature dependence dark conductivity measurements made on as-deposited PVA:n-CdS nanocomposites order identify the conduction mechanism. temperature activated process having single activation energy. Steady state photo-conductivity transient photoconductivity with intensity done different range. measurement shows that doped CdS good candidate for photovoltaic devices.
